Influence of superohmic dissipation on a disordered quantum critical point
Thomas Vojta, J. A. Hoyos, Priyanka Mohan +1
We investigate the combined influence of quenched randomness and dissipation on a quantum critical point with O(N) order-parameter symmetry. Utilizing a strong-disorder renormaliza…
Influence of spin fluctuations near the Mott transition: a DMFT study
Serge Florens, Priyanka Mohan, C. Janani +2
Dynamics of magnetic moments near the Mott metal-insulator transition is investigated by a combined slave-rotor and Dynamical Mean-Field Theory solution of the Hubbard model with a…
Evidence for power-law Griffiths singularities in a layered Heisenberg magnet
Fawaz Hrahsheh, Hatem Barghathi, Priyanka Mohan +2
We study the ferromagnetic phase transition in a randomly layered Heisenberg model. A recent strong-disorder renormalization group approach [Phys. Rev. B 81, 144407 (2010)] predict…
An Anomalously Elastic, Intermediate Phase in Randomly Layered Superfluids, Superconductors, and Planar Magnets
Priyanka Mohan, Paul M. Goldbart, Rajesh Narayanan +2
We show that layered quenched randomness in planar magnets leads to an unusual intermediate phase between the conventional ferromagnetic low-temperature and paramagnetic high-tempe…
